Abstract

A 3D-shift multiplexing is reported with converging signal and diverging random phase coded reference beam into the Cu:Ce:Tb:CLN crystal. Shift-selectivity at first null along x,y and z-axis is measured to be 1.5, 5 and 5mm for random phase-coded reference beam. Low capacity data page with only 1-4 kbits were successfully recorded/retrieved and the achievable raw areal density of >350 Gbit/in2 will be reported.
